Actually, the skits and performances are exactly the same for both days. Occasionally, one of the presenters (the people who announce the skits) can only come for one performance, but that is unusual.
The main difference between the two shows is that the Tuesday show is when they announce the results of the judging (of best skit and best Easter Bonnet) and the fundraising totals. They usually have celebrity judges and celebrity announcers of the awards and totals, and I imagine those people are only there on Tuesday. But the rest of the show, for all intents and purposes, is exactly the same.
The fundraising period is typically six weeks, with the last fundraising on the Sunday before the Easter Bonnet performances. Shows don't always start exactly at the six week mark, though.
